SDO_GCDR.GEOCODE

Format

SDO_GCDR.GEOCODE_ALL(
     gc_username  IN VARCHAR2, 
     addr_lines   IN SDO_KEYWORDARRAY, 
     country      IN VARCHAR2, 
     match_mode   IN VARCHAR2 
     ) RETURN SDO_ADDR_ARRAY;

Description

Geocodes all addresses associated with an unformatted address and returns the result as an SDO_ADDR_ARRAY object.

Parameters

gc_username: Name of the user that owns the tables containing the geocoding data.
addr_lines: An array of quoted strings representing the unformatted address to be geocoded. The SDO_KEYWORDARRAY type is described in SDO_KEYWORDARRAY Type.
country: Country name or ISO country code.
match_mode: Match mode for the geocoding operation. Match modes are explained in Match Modes.

Usage Notes

This function returns an object of type SDO_ADDR_ARRAY, which is described in SDO_ADDR_ARRAY Type. It performs the same operation as the SDO_GCDR.GEOCODE function; however, it can return results for multiple addresses, in which case the returned SDO_ADDR_ARRAY object contains multiple SDO_GEO_ADDR objects. If your application needs to select one of the addresses for some further operations, you can use the information about each returned address to help you make that selection.

Each SDO_GEO_ADDR object in the returned SDO_ADDR_ARRAY array represents the center point of each street segment that matches the criteria in the addr_lines parameter. For example, if Main Street extends into two postal codes, or if there are two separate streets named Main Street in two separate postal codes, and if you specify Main Street and a city and state for this function, the returned SDO_ADDR_ARRAY array contains two SDO_GEO_ADDR objects, each reflecting the center point of Main Street in a particular postal code. The house or building number in each SDO_GEO_ADDR object is the house or building number located at the center point of the street segment, even if the input address contains no house or building number or a nonexistent number.

Examples

The following example returns an array of geocoded results, each result reflecting the center point of Clay Street in all postal codes in San Francisco, California, in which the street extends. The resulting array includes four SDO_GEOR_ADDR objects, each reflecting the house at the center point of the Clay Street segment in each of the four postal codes (94108, 94115, 94118, and 94109) into which Clay Street extends.
